You have to give more details about your process but following are the some of the general issues with condensers:

  • If the shell and tube condenser is water cooled then it could be fouled with dead crabs, mud, grass stalks, etc and needs to be back flushed.
  • Cooling water flow rate check for low rate can couse foulling as well.
  • A bypas arround the conderser is leaking vapor to the accumulator drum.
  • Insufficient drain of refrigerant from the condenser to the accumulator.
  • Subcooling of refirigerent liquid in the condenser reduces the heat transfer surface.
